Ulnar Collateral Ligament Insertional Injuries in Pediatric Overhead Athletes: Are MRI Findings Predictive of Symptoms or Need for Surgery? Feb 01, 2019

Show notes

Tony Wong discusses his study on how to determine whether ulnar collateral ligament insertion below the articular margin exists in the pediatric population and whether MRI features can be used to identify insertional UCL injuries in overhead athletes that are symptomatic or require surgery.

The Relevance of Ulnar-Sided Contrast Extravasation During Radiocarpal Joint Wrist Arthrography Jan 18, 2019

Show notes

Contrast material often extends from the radiocarpal joint into the proximal soft tissues adjacent to the ulnar aspect of the ulnar styloid during single-compartment radiocarpal joint MR arthrography of the wrist. Jack Porrino discusses his recent study that hypothesized this is a common finding unrelated to symptoms or examination technique.
